GENITO-URINARY DISEASE. —In functional leucorrhcea, due to excessive secretion of the glands of the cervix uteri, the vaginal injection of a weak solution of the bicarbonate (1 drachm to 1 pint) will give relief; when the dis charge is like the white of an egg or lumpy, three or four injections will often cure; but, when the discharge is yellow and puriform, these injections may fail, although, in many cases, when this yel low discharge is due to a mere abrasion of the os uteri, these injections, con tinued for a week or two, will change the yellow to a white discharge. (Ringer.) Anti-emetics.—The citrate of potash is often serviceable as an anti-emetic in doses of from drachm to 4 drachms; the official liquor potassii citratis is often preferred in doses of from 1 to S drachms.
In the nausea and vomiting of the first stage of acute bronchitis and of febrile affections in general the use of the citrate in the form of "neutral mixture" (liquor potassii citratis) or effervescent draught will allay the trouble. Effervescent draught is composed of two solutions: a solution of bicarbonate of potash (2 ounces to 1 pint) and a solution of citric acid (2 ounces to 1 pint), the dose being to 1 ounce of each solution, mixed when needed. .
Potassium Chlorate.—Potassium chlo rate is different from all the other salts of potassium, not only in its physiological action, but in its therapeutic effects. It is, perhaps, the most poisonous, with the exception of the cyanide. When locally
applied to the mucous membranes its action is that of an irritant, and when absorbed into the blood it causes de structive changes in it (meth2moglobin temia), and, if given in overdose, induces acute nephritis. It was formerly thought that chlorate of potash when taken into the system was decomposed and yielded a large amount of oxygen, but later ex periments have shown that it passes from the body unchanged. It should never be triturated with sulphur, tannin, char coal, or glycerin, as explosion is apt to follow.
STOMATITIS.—Chlorate of potash in solution (1 to 16) is used as a detergent mouth-wash and especially in mercurial salivation. The following solution is rec ommended for the latter use by Hare: Chlorate of potash, 48 grains; tincture of myrrh, drachm; elixir of calisaya, 3 ounces; of this mixture a teaspoonful may be taken every five hours, and may be used as a mouth-wash. In mem branous or ulcerative sore mouth, in children, the same mixture or the plain solution (1 to 16) may be employed in smaller dose. In aphthm the chlorate, finely powdered, alone or with powdered sugar, may be dusted on the patches. Dillon's antiseptic dentifrice contains chlorate of potash: Salol, chalk, charcoal, and powdered cinchona-bark, of each, 2 drachms; chlorate of potash,- 1 ounce.
